God led the descendants of Jacob out of Egypt and brought them through the Red Sea and into the wilderness and then gave them his Law, and also statues, ordinances and judgments by the hand of Moses.

And God declared to them at that time these words,

DEUTERONOMY 14:2

For thou art an holy people unto the LORD thy God, and the LORD hath chosen thee to be a peculiar people unto himself, above all the nations that are upon the earth.

But that promise was a conditional promise.

EXODUS 19:5-6

5. Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine: 6. And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.

But they Broke the Covenant and continued to trample upon the Holy Precepts of Jehovah and forsook the Statues, ordinances and Judgments spoken by Moses...and they continued and continued to neglect the conditions AND the terms of the Covenant.

The LORD then got tired of them trampling upon his Holy Covenant, so he sent the angel Gabriel to Daniel and gave him a probationery time line for them to repent and turn to him and keep his covenant or else they will cease to be his chosen people.

DANIEL 9:24

Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.

Question: Did the Israelities repent and return to God; to keep his Everlasting Covenant AND to perform the things that were written in the Book of the Law of Moses?

No they didn't, instead of returning to the Covenant of the LORD, they went and set up man made theories and man made commandments, and not only that; but, they did something even more rebellious than to just refrain from performing the things that were written in the Book of Moses. But they reject the very One who came to save them from their sins.

The One to whom all those sacrifices and ordinances that were written in the Book of the Law of Moses pointed to. AND in rejecting the Messiah they also rejected the New Covenant promise in (Jeremiah 31:31-33) which the angel Gabriel said the Messiah was to confirm with them.
